I got this app the peterson strobosoft tuner for the iphone. It is $9.99, pretty incredible fast tracking strobe tuner. It picks up drum notes really easily, and it has a noise filter to filter out room noise and background noise. I used it at my practice space with a band playing next door and it was still able to pick up the note just from the drum. It also shows what octave the note is which is really handy.

Pretty incredible for a $10 application.

It is kind of weird because you can tune all the lugs to a certain note and the overall note will be different.

I had used a strobe tuner before at a recording studio but they are big and expensive, this is highly portable.
